Frequently Asked Questions
Does homemade laundry detergent work in HE machines?
Yes, this low-sudsing recipe is HE-compatible. Use 2 tablespoons per load and ensure ingredients are fully dissolved before adding clothes. Never exceed 2 tbsp to prevent oversudsing.
How long does homemade detergent last?
Properly stored in an airtight container away from moisture, it lasts 6-12 months. Discard if clumping occurs (sign of moisture absorption). For longest shelf life, add 1/4 cup silica gel packets to the container.
Can I make this recipe without borax?
Absolutely. Omit borax and increase washing soda to 1.5 cups. For hard water areas, add 1/4 cup white vinegar to the rinse cycle. This creates a gentler formula ideal for sensitive skin while maintaining cleaning power.
Will this damage my washing machine?
No evidence shows properly made powder detergent damages machines. Key precautions: always use in the drum (not dispenser), pre-dissolve in cold water cycles, and run monthly maintenance washes with vinegar. Never use liquid castile soap versions which cause residue buildup.
